From Sound I am come to Sent, in the discourse whereof, your _Author_[1] is pleased to set down these following propositions: 1. _That smelling is hindred by cold and helped by heat_: 2. _That when the Wind bloweth from the object, the smell is the stronger, and when it blows from the sentient towards the object, the weaker, which by experience is found in dogs, that follow the track of beasts by the Sent_: 3. _That such bodies as are last pervious to the fluid medium, yield less smell then such as are more pervious_: 4. _That such bodies as are of their own nature odorous, become yet more odorous, when they are bruised_: 5. _That when the breath is stopped (at least in man) nothing can be smelt_: 6. _That the Sense of smelling is also taken away by the stopping of the nostrils, though the mouth be left open._ To begin from the last, I say, that the nose is like the other sensitive organs, which if they be stopt, the corporeal sensitive motions cannot take copies of the exterior objects, and therefore must alter their action of patterning to some other, for when the eye is shut and cannot perceive outward objects then it works to the Sense of Touch, or on the inside of the organ to some phantasmes; and so do the rest of the Senses. As for the stopping of breath, why it hinders the Sent, the cause is, that the nostrils and the mouth are the chief organs, to receive air and to let out breath: but though they be common passages for air and breath, yet taste is onely made in the mouth and tongue, and sent in the nose; not by the pressure of meat, and the odoriferous object, but by patterning out the several figures or objects of sent and taste, for the nose and the mouth will smell and taste one, nay several things at the same time, like as the eye will see light, colour, and other objects at once, which I think can hardly be done by pressures; and the reason is, that the sensitive motions in the sensitive organs make patterns of several objects at one time, which is the cause, that when flowers, and such like odoriferous bodies are bruised, there are as many figures made as there are parts bruised or divided, and by reason of so many figures the sensitive knowledg is stronger; but that stones, minerals, and the like, seem not so strong to our smell, the reason is, that their parts being close and united, the sensitive motions in the organ cannot so readily perceive and pattern them out, as those bodies which are more porous and divided. But as for the wind blowing the sent either to or from the sentient, it is like a window or door that by the motion of opening and shutting, hinders or disturbeth the sight; for bodies coming between the object and the organ, make a stop of that perception. And as for the Dogs smelling out the track of Beasts, the cause is, that the earth or ground hath taken a copy of that sent, which copy the sensitive motions in the nose of the Dog do pattern out, and so long as that figure or
